Clear Casting Resin with MEK-P Catalyst – Great for Casting Small Parts!

This product is meant for small to medium castings that require both UV Resistance and a very hard cure. This product gels in around 20 minutes at 77 degrees and is able to be de-molded in around 2-3 hours. This product is not recommended for Silicone Molds, but does create a crystal-clear finish that is hard and machineable in just a few hours!

For Table Top coatings or River Tables, see our Liquid Glass or Superclear Epoxies. 

Polyester Clear Casting Resin Instructions:

  1. Set your mold or cast on a level surface, allowing for air movement as this product does produce heat when curing.
  2. Mix MEK-P Catalyst at 1.5%-2% by volume, thoroughly stirring with a stir stick, ensuring you don’t add air bubbles into the mix. Mix thoroughly like you are stirring coffee or tea for 3 minutes and then quickly get the resin out of the mixing cup and into your project. This product will kick off quickly, especially in mass.
  3. Once poured, you can make several quick passes with a heat gun to remove any surface bubbles.
  4. Product will gel with 1.5% MEK-P in around 20-25 minutes at 77 degrees, with warmer temperatures meaning less working time.
  5. The product should be hard and tacky in around 2 hours, with demolding available in around 12 hours. Catalyst Chart

    “I love fiberglass coatings. They have great products and excellent advice. I'm trying to open a boat repair shop in St . Mary's, GA and my supply WILL come from fiberglass coatings. When I lived in the Fl. Keys for 36 years and worked for a towing and salvage Co for 15 years all our supplies came from Fiberglass coatings. Great service and never were disappointed. Keep up the great job everyone.”

    “Been working on a skiff project and using all FGCI products. They came highly recommended by my friends who are boat builders. It is the highest quality resins, glass, and gelcoat for the money. They made it really easy for a newer person to boat building. The customer service is phenomenal and they are always knowledgeable and ready to help with any questions I had.”
